Shizuka Fujiyama serves as crew member thirteen aboard the Daiku Maryu. She possesses notable superhuman strength, enabling her to lift weights far exceeding the capabilities of other crew members despite her lack of visible musculature. This deceptively immense physical power defines her essential role within the vessel. Her responsibilities center on mechanical maintenance and repairs, embodying the "Wrench Wench" archetype as she contributes directly to the ship's upkeep and operational functionality.
